REFRIGERATOR AND FiLTER.

EPECIPICATION forming part of Letters Patent No. 314,597, dated March 31, 1885.

Application filed July 10, 1883. I (No model.)

To aZZ whom it may concern:

Be it known that 1, ANDREW lVIOCLAIN, a citizen of the United States, residing at Nash ville, in the county of Davidson, in the State of Tennessee, have invented a new and useful Improvement in Refrigerators and Filters, of which the following is a'specification, reference being had to the accompanying drawings, in which-- Figure 1 is a representation of a vertical section of the entire apparatus. Fig. 2 is a top view of the same with the lid removed. Fig. 3 is also a top View of the same with the lid and the water-receptacle both removed. Fig. 4 is a vertical section of the entire apparatus, taken on the line a; of Fig. 1..

The object of the invention is the construction of a combined refrigerating and filtering apparatus having one filtering-chamber and a series of separate refrigerating-chambers independent of and having no communication with each other by means of doors or other openings, and so combined with said filtering-chamber and the other parts herein described that they will be kept at a cold temperature while the ice used is dissolving and long after the ice has dissolved, while the water used for refrigeration shall at the same time be filtered and pass off into a tank below to be drawn off for use.

The invention is designed as an improvement on the device shown in Patent N o. 188, 650, granted to me March 20, 1877; audit consists in the peculiar combinations and the construction and arrangement of parts, hereinafter more fully described, and then specifically pointed out in the claims.

In the accompanying drawings only two refrigerating-chambers are represented, but of course the number may be increased, if desired, by lengthening the filtering-chamber and the entire apparatus proportionately and introducing additional partition-walls, as hereinafter described.

Referring now to the details of the drawings, A represents a water-tank, which supports the entire superstructure B, which, through resting on the tank A, is not attached to it. The superstructure B consists of the refrigerating-chambers H and H, filteringchamber is, tube m, tray n, and three watercompartments, 1 2 3, which so communicate with each other as to form one general watercompartment, as followsviz., the water-compartment 1, which also forms an ice-receptacle, situated immediately under the opening 0, communicates below the water-compartwater-receptacle G fits loosely, and. rests on the 1 top of the inner vertical wall, Z, of the filtering-chamber It, and on the top of tray 11, and on the stops P,fixed in the front corners of superstructure B, and is supplied with handles, by which it may be let down into said superstructure B and withdrawn at pleasure.

H H represent the refrigerating-chambers formed on the bottom plate, B, of the superstructure B, and are in dependent of each other. The endwalls, b, of superstructure B serve as the outer walls of chamber H and of the chamber k, situated at the other end of the row of refrigerating-chambers. Chamber H does not extend to chamber 70, and thus leaves a space which forms the water-compartment lbetween the rear wall of chamber H and the inner wall of chamber h. The chambers H H are provided each respectively with doorsh h, cut in the front wall of the superstructure" B;

The wall l, which serves as the inner wall of the chamber It and rear wall of chamber H, rises vertically from the bottom of superstructure B toa line which is level with the top of tray a, and extends from one end wall to the other end wall, and parallel with the rear wall, 9; This wall has an opening, Z, of rectangular shape,formed in its lower edge at the end opposite chamber H, to afford a communication between the water-compartments l and 2.

The rear and end walls of superstructure B serve as the outer and end walls of chamber is, respectively. The bottom of chamber k is perforated at one end, and placed at such a distance above the bottom of superstructure B as to leave a space, which forms the water compartment 2.

A vertical tube, at, is firmly attached to the rear wall of the superstructure B, with its upper end attached to the bottom of the tray a, from whence it passes through the por-' tion of chamber 7t: oppositeits perforated bottom, with its lower end communicating with the water-compartment A when the superstructure B is placed thereon.

The tray 1% is situated at the upper corner of the chamber 70, with its bottom slightly higher than the top of the refrigerating-chainbers H and H, and is formed with two vertical perforated walls, set at right angles to each other, and attached-to the rear and end walls of superstructure B.

The receptacle 0 is'furnished with a spongebox, D, attached to its bottom, and bordering on inner extremity of the opening 0. Said box is formed by two sides, D, of triangular shape, with their basesattached to the bottom of receptacle 0, the vertical edges of which are joined by parallel walls 12 d perforated at their lower ends, the inclined edges being joined at their top by a plate, Q, which zocovers only a portion of said edges, the remaining portion being covered by a perfo-v rated plate, Q,'hinged to the bottom of chamher 0, said perforated plate being locked in position by a slide, q, working in guides g on the plate Q. A slide, 2', working between the walls d d", regulates the fiow of water through the sponge-box D. Sponge or other filtering material being firmly compressed into the box D, the perforated lid is let down and fastened by the slide q, which is slipped over its upper edge.

An opening, 0, of rectangular shape, is formed in the bottom of receptacle 0, and is provided with wall 0, rising vertically from its edges to the top of the walls of the receptacle C. One of the walls of the receptacle 0 forms one of the end walls inclosing the opening 0, the inner wall being formed by the perforated wall d of the sponge-box.

4.0 The walls inclosing and surrounding the opening 0 are provided with a top or lid, L, hinged to the upper edge of one of the side walls.

' The receptacle 0 being placed in position,

5 the opening 0 comes directly over the watercompartment 1. Through this opening ice is dropped into the water-compartment l. The

7 opening 0' is made a little smaller than this water compartment, so that ice dropped through the opening 0 may not strike the edges of chambers H and H. Water being poured into receptacle 0, percolates through the sponge or other filtering material in the box D, and is regulated in its flow there- 5 5 through by the sllde 42, closing or disclosing the apertures f and g in. the walls (2 d respectively. The water passes through the opening 0' into the watercompartment 1 below. Qhamber It being well packed with fine 6e gravel and charcoal or other suitable filtering material, the water rises faster in the general water-compartment than in chamber it; but the inner vertical wall, 1, of chamber is being higher than the level of the top of the tube 111. the water will be held in the general watercompartment till it has time to sink to the level of the top of the tube m. When it has sunk to the level of the top of the tube m, it can sink no lower, and as the top of chambers H H is lower than the level of the top of the tube m these chambers will remain submerged in ice-water. Suitable filtering material being used-such as gravel and charcoalit will' assume the icewater temperature, and will retain that temperature and part with it more slowly than the water could do without its presence and contact. The walls of superstructure B are surrounded with double casing, with space between the casings, into which paper, charcoal, or other non-conductor of heat is to be placed. The walls of superstructure B being thus surrounded and its top closed with the lid 0, and the chambers H H and the chamber and the water-compart ments being all situated below the water-rcceptacle O, the water in said receptacle 0 is first brought to an ice-water temperature, and the slide t is then elevated, so as to admit a gentle flow into the water-compartments below. The ice in the compartments below will dissolve slowly, and the chambers H H and their contents will retain a cold temperature while the ice below is dissolving, and long after it has dissolved.

The water .in superstructure B may be entirely removed and the-chamber 7o drained,

when it is desired to do so, by placing a piece of hose over the edge of one of the walls of ro5 superstructure l3 and extending it down through opening 0, to the bottom, and ex tending it on the outside down to a point which is lower than the bottom of superstructure B, thus forming a siphon.

What I claim as new is- 1. The combination, with a series of refrigerating-chambers, as H H, an ice-receiver, as 1, water-compartment, as 3, and a filter, as k, of the water-receptacle 0, extending over the refrigerating-compartments, the icereceiver, the water-compartment, and the filteringchamber, substantially as described.

2. The combination, with a series of submerged refrigerating-chambers, as HH, and I20 a filtering-chamber, of an ice-receiver partially surrounded by said refrigerating and filtering chambers, substantially as described.

3. Acombined refrigerator and filter consisting of a series of refrigerating-chambers, as H H, filter 7c, and ice-receiver 1, in combination with a water-receptacle, as 0, located over said parts and provided with an'opening, 0, coincident with the ice-receiver l, as and for the purposes set forth.

. 4. Inv combination with a series of refriger- 'ati ng-chambers, as H H, ice receiver 1, and filter lo, a water-receptacle, as 0, located over said parts and provided with an opening, 0',

coincident with said receiver, said opening being iuclosed or surrounded on three of its sides by vertical walls, and on the fourth by a filtering-box, as D, substantially as and for the purposes specified.

5. The combination, with a series of refrigeratingchambers, as H H, and an ice-receiver, as l, of a water-receptacle arranged above the ice-receiver and refrigerating-chambers, and provided with a passage through it of smaller diameter than the ice-receiver, substantially as and for the purpose specified.

6. The combination, in a combined refrigererator and filter, of a series of refrigeratingchambers' and a water-co xnpartment with the tray n and tube m, the upper end of the tube extending above the top of said chamber, and its lower end extending below the bottom of the same, substantially as shown, and for the purpose described.
